質問を例の .Rnw コード ブロック内に置くことにします。これを .pdf ファイルにコンパイルすると、問題が最も簡単にわかります。私は pdfLaTeX と knitr を使用して、RStudio 内からファイルをコンパイルしています。コード チャンクは、ドキュメントの一部となるプロットを描画するように R に指示するなどの処理を行っている可能性があるため、R でも実行されることが重要であることに注意してください。

\section*{Question Part 1.}
I am writing this document inside RStudio, using Sweave. I want everything
in the document to be doublespaced with the exception of R code chunks,
which I want to be singlespaced for the sake of tidiness and saving space.
It is important that the code chunks also run in R, since they may be doing
things like telling R to draw plots which will be part of the document.
\section*{Question Part 2.}
The problem that I seem to be having is that when I put in a command to
begin singlespacing and a command to end single spacing around an R code
chunk, text that is not inside the begin and end singlespacing command, for
some reason, ends up being singlespaced as well, even though as far as I can
tell it should be doublespaced, as can be seen with the text in this very
paragraph (if you've compiled it into a .pdf).
\begin{singlespacing}
<<echo=TRUE>>=
k=3
mse=0.347
d=0.85
alpha=0.05
n=30
pwr.df=data.frame(row.names = 1:n)
pwr.df$n=1:n
@
\end{singlespacing}
Strangely, the problem doesn't occur for text which follows the "end" of the
singlespacing commmand, but text which comes before the 'begin'
singlespacing command is affected, as can be seen here.

問題の原因が何なのかはわかりませんが、コードを 内に記述すると、minipage期待どおりに動作します。
